Oscillating Hadron and Jet Multiplicity Moments *
نویسنده
چکیده
Recently, the moments of multiplicity distributions in ee annihilation and the ratios Hq (cumulant over factorial moments Kq/Fq) have been determined both for the hadronic final state and for jets at variable resolution. These ratios show an oscillatory behaviour as function of q with strong dependence of the amplitude and length of oscillation on the jet resolution parameter ycut. The recent explanation of this phenomenon based on perturbative QCD calculations is discussed.

QCD and hybrid NBD on oscillating moments of multiplicity distributions in lepton- and hadron-initiated reactions
Abstract QCD predictions for moments of multiplicity distributions are compared with experimental data on e+e− collisions and their two-NBD fits. Moments of the multiplicity distribution in a two-NBD model for 1.8 TeV pp-collisions are considered. Three-NBD model predictions and fits for pp at LHC energies are also discussed. Analytic expressions for moments of hybrid NBD are derived and used t...
متن کاملQcd Evolution of Hadron and Jet Multiplicity Moments *
We describe recent applications of the MLLA evolution equations to the calculation of mean multiplicities in quark and gluon jets and the higher moments of hadron and sub-jet multiplicity distributions in e + e −-annihilation as function of c.m.s. energy Q and resolution parameter ycut. The transition from jets to hadrons with increasing jet resolution is considered.
متن کاملQCD explanation of oscillating hadron and jet multiplicity moments
Ratios of multiplicity moments, Hq (cumulant over factorial moments Kq/Fq), have been observed to show an oscillatory behaviour with respect to order, q. Recent studies of e+e− annihilations at LEP have shown, moreover, that the amplitude and oscillation length vary strongly with the jet resolution parameter ycut. We study the predictions of the perturbative QCD parton cascade assuming low nonp...
متن کاملMultiplicity Moments in Qcd and Experiment
QCD predictions for moments of parton multiplicity distributions are discussed. The next-to-leading terms and conservation law give rise to the peculiar oscillating shape of some ratio of the moments. The similar shape has been found by moment analysis of hadron multiplicities. Experimental data, theoretical Monte Carlo models and phenomenological fits have been used for ee, hh, hA, AA reaction...
متن کاملMoments of the Charged-particle Multiplicity Distribution in Z Decays at Lep
The charged-particle multiplicity distribution and its moments have been measured, for all hadronic as well as for light-quark and b-quark events in ee collisions at the Z mass. The Hq moments derived from the charged-particle multiplicity distribution are known to exhibit quasi-oscillations when plotted versus the order of the moment. This behavior is predicted by the NNLLA of perturbative QCD...
